Description

La présente invention concerne une douille de fixation pour l'assemblage d'au moins deux structures préalablement percées, ladite douille s'étendant selon un axe principal entre une première et une deuxième extrémités ouvertes, ladite douille comprenant un corps sensiblement cylindrique et une tête élargie, ladite tête élargie comprenant des premières surfaces de montage aptes à s'assembler à un premier élément d'installation et à bloquer en rotation ledit premier élément d'installation autour de l'axe principal.The present invention relates to a fixing sleeve for the assembly of at least two previously drilled structures, said sleeve extending along a main axis between a first and a second open ends, said sleeve comprising a substantially cylindrical body and an enlarged head. , said enlarged head comprising first mounting surfaces adapted to be assembled with a first installation element and to block said first installation element in rotation about the main axis.

L'invention s'applique particulièrement aux fixations temporaires de type agrafes d'épinglage.The invention is particularly applicable to temporary fixings of the pinning staple type.

Dans l'industrie aéronautique, avant de réaliser l'assemblage définitif de deux éléments de structure, il est connu de procéder à un assemblage provisoire desdits éléments au moyen de fixations temporaires insérées dans des trous traversants. De telles fixations temporaires sont notamment décrites dans le document EP2247862 .In the aeronautical industry, before carrying out the final assembly of two structural elements, it is known practice to carry out a temporary assembly of said elements by means of temporary fasteners inserted in through holes. Such temporary fixings are described in particular in the document EP2247862 .

Au cours du montage desdites fixations temporaires, un premier outil de montage bloque la douille en rotation dans le trou traversant tandis qu'un deuxième outil entraîne en rotation une vis disposée dans la douille. Ladite douille doit donc être bloquée solidement pendant le vissage, sous peine d'être elle-même entraînée en rotation.During the assembly of said temporary fasteners, a first assembly tool blocks the sleeve in rotation in the through hole while a second tool rotates a screw disposed in the sleeve. Said sleeve must therefore be securely blocked during screwing, otherwise it will itself be rotated.

Par ailleurs, dans le cas d'un montage des fixations temporaires réalisé par un automate, la fixation doit pouvoir être saisie et déplacée facilement par ledit automate.Moreover, in the case of mounting of the temporary fixings carried out by an automatic device, the fixing must be able to be grasped and easily moved by said automatic device.

Enfin, la fixation doit pouvoir être retirée complètement des trous traversants par un automate, même en présence de mastic disposé préalablement dans le trou, ayant potentiellement commencé à polymériser.Finally, the fastener must be able to be completely removed from the through-holes by an automatic device, even in the presence of mastic previously placed in the hole, which has potentially started to polymerize.

Les fixations temporaires du document EP2247862 présentent notamment des encoches en croix ménagées dans la tête de douille. Ces encoches peuvent être à l'origine d'un blocage insuffisant de la douille, notamment lorsqu'un couple important est exercé sur la vis. Par ailleurs, de telles encoches ne permettent pas à elles seules une préhension suffisante de la fixation par un automate, ce qui implique de munir ledit automate de moyens de préhension supplémentaires.Temporary fixings of the document EP2247862 in particular have cross notches formed in the socket head. These notches can be the cause of insufficient locking of the sleeve, in particular when a large torque is exerted on the screw. Moreover, such notches alone do not allow sufficient gripping of the binding by an automatic device, which implies providing said automatic device with additional gripping means.

D'autres dispositifs sont présentés dans EP3147520A1 , US3096678A , DE102015109278A1 et DE4400895A1 .Other devices are presented in EP3147520A1 , US3096678A , DE102015109278A1 and DE4400895A1 .

Dans les modes de réalisation représentés, l'élément d'accrochage 18 comprend quatre pattes 82 identiques.The fastening element 18 comprises a base 80 and at least two legs 82 connected to said base 80. In the embodiments shown, the fastening element 18 comprises four identical legs 82.

La base 80 de l'élément d'accrochage 18 a une forme sensiblement cylindrique et comporte une surface externe 84 de forme complémentaire de la surface interne 37 du corps 34. La base 80 est ainsi apte à coulisser dans la douille 12, 112 selon l'axe principal 14, tout en étant bloquée en rotation dans ladite douille.The base 80 of the fastening element 18 has a substantially cylindrical shape and comprises an external surface 84 of a shape complementary to the internal surface 37 of the body 34. The base 80 is thus able to slide in the sleeve 12, 112 according to l 'main axis 14, while being locked in rotation in said sleeve.

La base 80 comprend une ouverture centrale 86 disposée selon l'axe principal 14. L'ouverture centrale 86 est pourvue d'un taraudage complémentaire du filetage de la tige 64 de l'élément allongé 16.The base 80 comprises a central opening 86 arranged along the main axis 14. The central opening 86 is provided with a thread complementary to the thread of the rod 64 of the elongated element 16.

Les pattes 82 sont disposées autour de l'ouverture centrale 86 et s'étendent axialement à partir de la base 80, à travers la deuxième extrémité ouverte 32 de la douille 12, 112. Une extrémité de chaque patte 82 est formée par un bec d'accrochage 88.The tabs 82 are disposed around the central opening 86 and extend axially from the base 80, through the second open end 32 of the socket 12, 112. One end of each tab 82 is formed by a spout. 'hook 88.

Les pattes 82 et/ou leur jonction avec la base 80 présentent une certaine élasticité. Plus précisément, les pattes 82 sont déplaçables par rapport à l'axe principal 14 entre une position rétractée, dans laquelle les becs d'accrochage 88 sont au contact les uns des autres, et une position déployée, dans laquelle lesdits becs d'accrochage 88 sont écartés radialement les uns des autres.The tabs 82 and / or their junction with the base 80 have a certain elasticity. More precisely, the tabs 82 are movable relative to the main axis 14 between a retracted position, in which the hooking jaws 88 are in contact with each other, and a deployed position, in which said hooking jaws 88 are spaced radially from each other.

Les figures 2, 3 et 4 montrent la fixation 10, 110 en position rétractée ; la figure 5 montre la fixation 110 en position déployée.The figures 2, 3 and 4 show the binding 10, 110 in the retracted position; the figure 5 shows attachment 110 in the deployed position.

Dans la position rétractée et dans la position déployée, un diamètre maximal au niveau des becs d'accrochage 88 est respectivement inférieur et supérieur à un diamètre de la surface externe 36 du corps 34 de la douille 12, 112.In the retracted position and in the deployed position, a maximum diameter at the level of the hooking jaws 88 is respectively smaller and greater than a diameter of the outer surface 36 of the body 34 of the sleeve 12, 112.

La bague d'assemblage 20 est assemblée à l'ergot 68 de l'élément allongé 16 et à l'ouverture centrale 86 de la base 80 de l'élément d'accrochage 18 ; la bague d'assemblage 20 assemble ainsi l'élément allongé 16 et l'élément d'accrochage 18.The assembly ring 20 is assembled to the lug 68 of the elongated element 16 and to the central opening 86 of the base 80 of the fastening element 18; the assembly ring 20 thus assembles the elongate element 16 and the fastening element 18.

Plus précisément, la bague d'assemblage 20 est fixe axialement par rapport à l'ergot, étant bloquée de part et d'autre par la tige 64 et par la collerette de sertissage 72. Ladite collerette est pliée radialement vers l'extérieur après déformation.More precisely, the assembly ring 20 is fixed axially with respect to the lug, being blocked on either side by the rod 64 and by the crimping flange 72. Said flange is bent radially outwards after deformation. .

D'autre part, la bague d'assemblage 20 comporte une première 90 et une seconde 92 portions alignées axialement. Chacune des première 90 et seconde 92 portions a une surface externe cylindrique de révolution.On the other hand, the assembly ring 20 has a first 90 and a second 92 axially aligned portions. Each of the first 90 and second 92 portions has a cylindrical outer surface of revolution.

La première portion 90, disposée du côté de la tige 64, présente un diamètre externe inférieur ou égal à un diamètre minimal de l'ouverture centrale 86 de la base 80. Dans une configuration dite de débrayage de la fixation 10, 110, telle que représentée sur les figures 3 et 4, ladite première portion 90 est insérée dans ladite ouverture centrale 68.The first portion 90, disposed on the side of the rod 64, has an external diameter less than or equal to a minimum diameter of the central opening 86 of the base 80. In a so-called disengaging configuration of the binding 10, 110, such as represented on the figures 3 and 4 , said first portion 90 is inserted into said central opening 68.

La seconde portion 92, disposée du côté de la collerette de sertissage 72, présente au contraire un diamètre externe supérieur au diamètre minimal de l'ouverture centrale 86. Ainsi, une jonction entre les première 90 et seconde 92 portions forme une butée axiale par rapport à la base 80, empêchant une désolidarisation de l'élément allongé 16 et de l'élément d'accrochage 18 en configuration de débrayage.The second portion 92, disposed on the side of the crimping flange 72, on the contrary has an outer diameter greater than the minimum diameter of the central opening 86. Thus, a junction between the first 90 and second 92 portions forms an axial stop with respect to at the base 80, preventing the elongate element 16 from becoming detached from the hooking element 18 in the disengaged configuration.

De préférence, la première empreinte 40 de la tête élargie 35 de la douille 12, 112 et la partie frontale 212 du premier élément d'installation 204, 304 sont configurés pour s'emmancher de manière à solidariser temporairement la fixation 10, 110 et le nez de pose 202, l'axe principal 14 étant confondu à l'axe de pose 210.Preferably, the first recess 40 of the enlarged head 35 of the socket 12, 112 and the front part 212 of the first installation element 204, 304 are configured to fit so as to temporarily secure the fastener 10, 110 and the installation nose 202, the main axis 14 being coincident with the installation axis 210.

Plus précisément, la profondeur 45 de la première empreinte 40 est choisie suffisamment importante pour que les frottements entre ladite première empreinte 40 et la partie frontale 212 compensent le poids de la fixation 10, 110. Ladite fixation peut ainsi être transportée par l'automate équipé du nez de pose 202, 302 sans autre préhension que ledit nez de pose.More precisely, the depth 45 of the first recess 40 is chosen sufficiently large so that the friction between said first recess 40 and the front part 212 compensates for the weight of the binding 10, 110. Said binding can thus be transported by the equipped automaton. of the installation nose 202, 302 without any other grip than said installation nose.

Le nez de pose 202 des figures 5 à 9 va maintenant être décrit plus précisément. L'élément de blocage 209 est disposé à l'intérieur du premier élément d'installation 304. L'élément de blocage 209 est un manchon tubulaire, s'étendant selon l'axe de pose 210, entre une extrémité arrière 230 et une extrémité avant 232. Adjacente à ladite extrémité avant 232, l'élément de blocage 209 comporte une partie tubulaire centrale 233, dont un diamètre extérieur permet la rotation dudit élément de blocage à l'intérieur premier élément d'installation 204. L'extrémité avant 232 est réalisée sous la forme d'une collerette s'étendant radialement vers l'extérieur par rapport à la partie tubulaire centrale 223. La surface d'extrémité 216 du premier élément d'installation 204 est destinée à venir axialement au contact de ladite collerette 232.The nose fitting 202 of figures 5 to 9 will now be described more precisely. The locking element 209 is disposed inside the first installation element 304. The locking element 209 is a tubular sleeve, extending along the laying axis 210, between a rear end 230 and an end. front 232. Adjacent to said front end 232, the locking element 209 comprises a central tubular part 233, an outer diameter of which allows the rotation of said locking element inside the first installation element 204. The front end 232 is produced in the form of a collar extending radially outwardly with respect to the central tubular part 223. The end surface 216 of the first installation element 204 is intended to come into contact axially with said collar 232 .

Une surface radiale 234 de la collerette 232 présente une section identique à la surface radiale 214 de la partie frontale 212 du premier élément d'installation 204. Plus précisément, la surface radiale 234 présente une alternance de méplats 235 et de portions d'arcs 236. Dans une position dite d'installation, représentée à la figure 8, l'élément de blocage 209 est dans une première position angulaire par rapport au premier élément d'installation 204, telle que les méplats 235 et 215 sont alignés. Dans la direction de l'axe de pose 210, la longueur desdits méplats 235, 215 alignés est égale, aux jeux près, à la profondeur 45 de la première empreinte 40 de la douille 12, 212.A radial surface 234 of the flange 232 has a section identical to the radial surface 214 of the front part 212 of the first installation element 204. More precisely, the radial surface 234 has an alternation of flats 235 and of portions of arcs 236. In a so-called installation position, shown in figure 8 , the locking element 209 is in a first angular position relative to the first installation element 204, such that the flats 235 and 215 are aligned. In the direction of the laying axis 210, the length of said aligned flats 235, 215 is equal, except for clearances, to the depth 45 of the first recess 40 of the sleeve 12, 212.

La figure 9 représente une position dite de verrouillage du nez de pose 202. Dans ladite position de verrouillage, l'élément de blocage 209 est dans une deuxième position angulaire par rapport au premier élément d'installation 204 de sorte que les méplats 235 sont désalignés avec les méplats 215 dudit premier élément d'installation.The figure 9 shows a so-called locking position of the installation nose 202. In said locking position, the locking element 209 is in a second angular position relative to the first installation element 204 so that the flats 235 are misaligned with the flats 215 of said first installation element.

Un exemple de mécanisme d'entraînement en rotation de l'élément de blocage 209 est visible sur la figure 6. La partie arrière du premier élément d'installation 204 comporte au moins une ouverture latérale 240. Ladite ouverture latérale 240 s'étend autour de l'axe de pose 210 selon une portion angulaire correspondant au moins à un écart entre les première et deuxième positions angulaires de l'élément de blocage 209.An example of a mechanism for driving the locking element 209 in rotation can be seen on the figure 6 . The rear part of the first installation element 204 comprises at least one lateral opening 240. Said lateral opening 240 extends around the laying axis 210 according to an angular portion corresponding at least to a distance between the first and second angular positions. of the locking element 209.

Le nez de pose 202 comporte en outre au moins une goupille 242 disposée radialement dans l'ouverture latérale 240. Une extrémité interne de la goupille 242 est fixée à l'extrémité arrière 220 de l'élément de blocage 209. Une extrémité externe 244 de ladite goupille 242 forme une saillie radiale à l'extérieur du premier élément d'installation 204. La goupille 242 est apte à se déplacer dans l'ouverture latérale 240 autour de l'axe de pose 210.The nosepiece 202 further comprises at least one pin 242 disposed radially in the side opening 240. An inner end of the pin 242 is fixed to the rear end 220 of the locking element 209. An outer end 244 of said pin 242 forms a radial projection outside the first installation element 204. The pin 242 is able to move in the lateral opening 240 around the installation axis 210.

Le nez de pose 202 comporte en outre une bague tubulaire 250, disposée autour du corps 208 et de la partie arrière du premier élément d'installation 204. La bague 250 comporte une portion arrière 252 en saillie, par exemple moeltée ou rainurée pour faciliter sa préhension manuelle.The installation nose 202 further comprises a tubular ring 250, arranged around the body 208 and the rear part of the first installation element 204. The ring 250 comprises a projecting rear portion 252, for example moeltée or grooved to facilitate its installation. manual gripping.

A proximité d'une extrémité avant 254, la bague 250 comporte au moins un orifice 256, de forme sensiblement complémentaire à celle d'une section de la goupille 242. L'orifice 256 a par exemple une forme légèrement oblongue, s'étendant axialement.Near a front end 254, the ring 250 comprises at least one orifice 256, of shape substantially complementary to that of a section of the pin 242. The orifice 256 has for example a slightly oblong shape, extending axially. .

L'extrémité externe 244 de la goupille 242 est logée dans l'orifice 256. Ainsi, une rotation de la bague 250 par rapport au corps 208 du nez de pose 202 permet à la goupille 242 de se déplacer dans l'ouverture latérale 240 et d'entraîner en rotation l'élément de blocage 209. Une rotation manuelle de la bague 250 entraîne ainsi la rotation de l'élément de blocage 209 entre les positions d'installation et de verrouillage.The outer end 244 of the pin 242 is housed in the hole 256. Thus, a rotation of the ring 250 relative to the body 208 of the nosepiece 202 allows the pin 242 to move in the side opening 240 and to drive the locking element 209 in rotation. A manual rotation of the ring 250 thus causes the rotation of the locking element 209 between the installation and locking positions.

De préférence, le nez de pose 202 comporte deux ensembles ouverture latérale 240 / goupille 242 / orifice 256, lesdits deux ensembles étant disposés en vis-à-vis par rapport à l'axe 210.Preferably, the fitting nose 202 comprises two lateral opening 240 / pin 242 / orifice 256 assemblies, said two assemblies being arranged vis-à-vis with respect to the axis 210.

D'autres mécanismes de rotation de l'élément de blocage 209 peuvent être employés, notamment adaptés à la mise en rotation de l'élément de blocage par un automate.Other mechanisms for rotating the locking element 209 can be used, in particular adapted to the setting in rotation of the locking element by an automatic device.

Un procédé d'installation de la fixation 10, 110 à l'aide d'un nez de pose 202, 302 va maintenant être décrit. La fixation 10, 110 est initialement en configuration de débrayage. Dans le cas du nez de pose 202 des figures 5 à 9, ledit nez de pose est dans la configuration d'installation de la figure 8.A method of installing the binding 10, 110 using an installation nose 202, 302 will now be described. The binding 10, 110 is initially in the disengaging configuration. In the case of the nose fitting 202 of the figures 5 to 9 , said installation nose is in the installation configuration of the figure 8 .

Un automate équipé du nez de pose 202, 302 saisit la fixation 10, 110 en assemblant la partie frontale 212 du premier élément d'installation 204, 304 à la première empreinte 40 de la tête élargie 35 de la douille 12, 112. L'automate déplace ensuite la fixation 10, 110, ainsi assemblée au nez de pose 202, 302, jusqu'à une première et une deuxième structures à assembler, percées par un trou traversant.An automatic device equipped with the fitting nose 202, 302 grasps the fixing 10, 110 by assembling the front part 212 of the first installation element 204, 304 to the first recess 40 of the enlarged head 35 of the socket 12, 112. The The automaton then moves the binding 10, 110, thus assembled to the fitting nose 202, 302, to a first and a second structure to be assembled, pierced by a through hole.

L'automate introduit la fixation 10, 110 dans ledit trou traversant jusqu'à la mise en butée de la tête élargie 35 contre une face avant de la première structure. La douille 12, 112 est alors reçue dans le trou traversant et les becs d'accrochage 88 des pattes 82 dépassent de la deuxième structure.The automaton introduces the fastener 10, 110 into said through hole until the enlarged head 35 comes into abutment against a front face of the first structure. The sleeve 12, 112 is then received in the through hole and the hooking noses 88 of the tabs 82 protrude from the second structure.

La partie frontale 212 du premier élément d'installation 204, 304 exerce un effort axial contre la tête élargie 35 en direction de la première structure, afin de bloquer en rotation la douille 12, 112. L'automate introduit la pointe 222 du deuxième élément d'installation 206 dans la deuxième empreinte 70 de la tête 66 et exerce ensuite un couple de torsion sur l'élément allongé 16. La mise en rotation de la tige 64 conduit le filetage de ladite tige à s'engager dans le taraudage de l'ouverture centrale 86 de la base 80 de l'élément d'accrochage. L'élément allongé 16 se déplace axialement vers les becs d'accrochage 88 des pattes 82. La seconde portion 92 de la bague d'assemblage écarte alors radialement lesdits becs.The front part 212 of the first installation element 204, 304 exerts an axial force against the enlarged head 35 in the direction of the first structure, in order to block the sleeve 12, 112 in rotation. The automaton introduces the tip 222 of the second element. installation 206 in the second recess 70 of the head 66 and then exerts a torque on the elongated element 16. The rotation of the rod 64 causes the thread of said rod to engage in the internal thread of the rod. central opening 86 of the base 80 of the fastening element. The elongated element 16 moves axially towards the hooking jaws 88 of the tabs 82. The second portion 92 of the assembly ring then radially separates said jaws.

La rotation de l'élément allongé 16 est poursuivie jusqu'à ce que les becs d'accrochage 88 soient en appui axial contre une face arrière de la deuxième structure et que la tête 66 soit au contact du deuxième épaulement 52 et/ou de la rondelle élastique 22. Dans le cas de la douille 112, la rondelle 22 est prise en sandwich entre la tête 66 de l'élément allongé 16 et l'anneau de guidage 54.The rotation of the elongated element 16 is continued until the hooking jaws 88 bear axially against a rear face of the second structure and the head 66 is in contact with the second shoulder 52 and / or the spring washer 22. In the case of the socket 112, the washer 22 is sandwiched between the head 66 of the elongate member 16 and the guide ring 54.

Ainsi, la fixation 10, 110 solidarise l'une à l'autre les deux structures à assembler.Thus, the fixing 10, 110 secures the two structures to be assembled together.

Un procédé similaire, avec une rotation de l'élément allongé 16 en sens opposé, permet de désolidariser la fixation 10, 110 du trou traversant desdites structures. La fixation 10, 110 peut ainsi être réutilisée.A similar process, with a rotation of the elongated element 16 in the opposite direction, makes it possible to separate the fixing 10, 110 from the through hole of said structures. The binding 10, 110 can thus be reused.

Dans le cas du nez de pose 202 des figures 5 à 9, une variante au procédé ci-dessus permet de verrouiller la fixation 10, 110 audit nez de pose pour en faciliter le transport.In the case of the nose fitting 202 of the figures 5 to 9 , a variant of the above method makes it possible to lock the binding 10, 110 to said fitting nose to facilitate transport.

Plus précisément, selon ladite variante, un opérateur saisit la fixation 10, 110, et insère la partie frontale 212 du premier élément d'installation 204 et la collerette 232 de l'élément de blocage 209 dans la première empreinte 40 de la tête élargie 35 de la douille 12, 112. Les méplats 215, 235 sont alors alignés avec les méplats 46 de la douille 12, 112. L'opérateur tourne la bague 240 dans un sens, de sorte que l'élément de blocage 209 atteigne la position de verrouillage représentée en figure 9. Dans cette position, les portions d'arc 236 de la collerette 232 sont disposées dans le volume en creux 47 de la surface interne cylindrique 42 de la première empreinte 40, entre l'épaulement 44 et une extrémité axiale des méplats 46. Ainsi, la douille 12, 212 est bloquée axialement à l'intérieur du nez de pose 202 et peut être transportée dans n'importe quelle direction horizontale ou verticale jusqu'aux première et deuxième structures à assembler.More precisely, according to said variant, an operator grasps the fixing 10, 110, and inserts the front part 212 of the first installation element 204 and the flange 232 of the locking element 209 in the first recess 40 of the enlarged head 35 of the socket 12, 112. The flats 215, 235 are then aligned with the flats 46 of the socket 12, 112. The operator turns the ring 240 in one direction, so that the locking element 209 reaches the position of lock shown in figure 9 . In this position, the arc portions 236 of the flange 232 are arranged in the recessed volume 47 of the cylindrical internal surface 42 of the first recess 40, between the shoulder 44 and an axial end of the flats 46. Thus, the socket 12, 212 is axially locked within nosepiece 202 and can be transported in any horizontal or vertical direction to the first and second structures to be assembled.

Une fois la fixation 10, 110 solidarisée aux structures à assembler, l'opérateur tourne la bague 250 dans l'autre sens, de sorte à replacer l'élément de blocage 209 en position d'installation puis à débloquer axialement la fixation 10, 110 du nez de pose 202.Once the binding 10, 110 is secured to the structures to be assembled, the operator turns the ring 250 in the other direction, so as to replace the locking element 209 in the installation position and then to axially unlock the binding 10, 110 of the nosepiece 202.

Le verrouillage axial de la fixation 10, 110 dans le nez de pose 202 par l'élément de blocage 209 permet le transport de la fixation 10, 110 dans n'importe quelle direction sans risque de perte de ladite fixation. Il permet également le retrait de la fixation 10, 110 des deux structures en exerçant simplement une traction sur le nez de pose 202, même si du mastic interposé entre les structures à assembler a durci autour de la douille 12, 112.The axial locking of the binding 10, 110 in the nose 202 by the locking element 209 allows the transport of the binding 10, 110 in any direction without risk of loss of said binding. It also allows the removal of the fastener 10, 110 of the two structures by simply exerting a traction on the installation nose 202, even if the mastic interposed between the structures to be assembled has hardened around the socket 12, 112.
